The experience of replacing a split system HVAC was an entirely new one for me and one that I was not thrilled about. However, Faris and his crew at Haha's Heating and Cooling made it an easy process from start to finish. I received an excellent quote and everyone was super professional and informative. The work was done efficiently and very well. The stress that can come with such an event was eased by the awesome way everyone at Haha's showed up and I couldn't be more grateful. I highly recommend this company to anyone! Thank you to Faris, Damien, Kaleb, Juan and the rest of the crew for all of their hard work and getting me back up and running in short order. You guys are much appreciated! Mohammad Abuasbah2025-05-06Trustindex verifies that the original source of the review is Google. Got a new ac unit back in January, had to call them back because the ac drain hose was clogged which cause water damage. They never cleaned or checked the hose when installing the new ac unit. They charged me for something they were supposed to do in the first place. When I asked them why are you charging me they said it’s not included for them to check on it even tho we paid for a brand new unit. david schmidt2025-05-05Trustindex verifies that the original source of the review is Google.

Why Switch to a Tankless Water Heater
Tankless water heaters—also known as on-demand water heaters—heat water only when you need it. That means no more keeping a large tank full of water heated 24/7. The result? Lower energy consumption, longer system lifespan, and instant hot water at any time.
Here’s what you’ll gain with a tankless unit:
- Endless Hot Water
- Reduce energy usage by up to 30%
- Save valuable space with wall-mounted designs
- Long Lifespan
- No tank means no sediment buildup

How Do Tankless Water Heater Work?
Tankless systems use powerful electric or gas burners to heat water as it flows through the unit. This eliminates the need to store hot water in a tank and eliminates “standby heat loss.” When you turn on a faucet, the system instantly starts working—delivering fresh, hot water within seconds.
They’re perfect for:
- Homes with high daily water usage
- Large families
- Smaller homes with limited space
- Homeowners focused on eco-friendly upgrades
Signs You Need a New Water Water Heater?
Not sure if it’s time to switch? Here are some common signs that your old water heater is on its last legs:
- Water turns cold quickly or takes too long to heat up
- Your utility bills are rising without explanation
- Strange noises coming from your tank
